This lesson was based off of equations that we had to find if the solution was true. We did this by solving the equation then testing it to see if the variable solution was true or false. A formula is an equation starting a relationship between 2 or more quantities. In simpler terms it helps you to solve the problem by using the equation given.

This section is all about solving one-step equations. Basically you identify what is happening to the variable in the equation and then do the opposite operation. For example: 16f = 80, so because you are taking 16 times f, you have to do the opposite. So you'd divide 16f by 16 and you have to do the same for the other side (80 divided by 16). Then you are left with f = 5. - Stephanie G.
This section is about one step equations. What you do to solve these problems is you take the opposites of what ever the equation has in it so that you get the variable by itself. Nicholas C.

This lesson was about how to create a mathematical model to describe a situation. There are four different types of models. The first one is a model which is a physical or numerical representation of a real world situation. A mathematical model uses numbers in a table to describe a situation. An algebraic model uses a model that includes one or two more variables written as an equation. And a rule is another name for a formula or equation. To do these, we need to use the Five-Step Plan, which includes, Step one- read through the problem piece by piece. Step two- plan by using the parts of a problem to figure out what needs to be done. Step three- set up and solve the problem. Step four- answer and make sure you've answered each equation. And Step five- check and make sure your answer and work make sense. -Erica M. :)

Chapter 3-4 is about two step equations. A two-step equation is a problem that uses two-steps to find the answer of a problem. For example- 3x-7=14
you add 7 by each side. Then you get 3x=21, finally you dived each side by 3 and get and answer of X=7.

This section is all about writing and solving proportions. A proportion is an equation where two ratios are the same. For example, A is to B as C is to D. You can also use fraction's to represent a proportion or a ratio. For instance, A/B=C/D. Another way to show what this lesson is about is with this example, x/24=24/36. First, you simply cross multiply. So, 24 and 24 get multiplied together for a total of 570. Then you take X and multiply that to 36. So now you have 36X=570. From here, you divide both sides by. Once that is done, you have your answer of X=16. Finally, check your work by plugging 16 in for X. 16/24=24/36.

In section 3-6 we learned how to graph inequalities on a number line and how to decifer if its either a false inequality or true equality. Several signs we use for telling what the inequality is are: at least ≥, at most ≤ greater than >, less than <, maximum ≤, and minimum ≥. For not equal to you use ≠. PJ Ramsey

This section is about squares and square roots. If you had an equation that says xsquared, you then do the opposite and the opposite is the square root.
